Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check fluid level; if low, top off with the correct type of ATF as specified in the owner's manual.
If the fluid is dark or has a burnt smell, proceed to replace it.
Place a drain pan under the transmission pan and remove the pan bolts carefully.
Allow the old fluid to drain completely, then replace the filter if applicable.
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).

3. Inspect and Repair Transmission Components

If the fluid is fine, check the transmission solenoids and wiring harness for any signs of damage or corrosion.
If issues are found, replace the faulty solenoids or harness as needed.
For slipping or lack of engagement, consider replacing the entire transmission or repairing internal components based on diagnostic results.
